Ex-stock medium & high-voltage industrial electric motors up to 20 MW & 13.8 kV. In-house mechanical and electrical adaptations delivered in days, not months.
Unplanned drive failures in cement plants, steel mills, power stations, or chemical complexes cause millions in downtime losses. Menzel delivers high-performance industrial replacement motors directly from stock in record time.
MENZEL Elektromotoren maintains one of Europe's largest independent inventories of large industrial motors. With thousands of low, medium, and high-voltage motors stored at our Berlin Hennigsdorf facility, we ensure your production is restored rapidly.
Unlike standard OEMs with 6-to-12 month delivery lead times, our modular inventory combined with in-house precision machining allows us to adapt and ship standard and special design motors within days or weeks.

To evaluate mechanical and electrical interchangeability immediately, our engineering team requires:
What doesn't fit directly will be engineered to fit immediately. Our state-of-the-art Hennigsdorf plant provides complete technical modifications under one roof.
Custom shaft extensions, special mounting flanges (V1/B3/B35), foot adapter plates, and modified terminal box positions to match existing foundation dimensions without site modifications.
Stator coil rewinding for non-standard voltages, special frequency matching (50 Hz / 60 Hz), tropical insulation treatments, space heater installations, and embedded RTD temperature sensors.
Every modified emergency replacement motor undergoes rigorous routine and load testing at our state-of-the-art 25 MW test field. Live online video observation available for international plant managers.
Is your damaged motor an obsolete series from an OEM that no longer exists or offers unacceptable lead times? Menzel manufactures exact mechanical drop-in replacements.
We regularly replace legacy high-voltage slip-ring and squirrel-cage motors from major global manufacturers. Our engineering team replicates original foot locations, shaft heights, shaft end dimensions, and electrical performance curves to ensure seamless replacement.
Delivering heavy industrial motors up to 20,000 kg worldwide via charter flights and express heavy-haul transport.
In-house export team managing immediate customs clearance, ATLAS export handling, and BAFA export licensing.
Heavy-duty seaworthy and air-freight compliant wooden crating according to IPPC / ISPM 15 standards.
Direct cooperation with cargo airlines to fly multi-ton high voltage motors directly to overseas industrial sites.
Global field service engineers ready to support mechanical alignment, wiring, and start-up on request.
Real-world examples where Menzel saved critical heavy industrial operations from catastrophic downtime.
When a ball mill drive failed at a high-altitude mine in the Peruvian Andes, Menzel supplied a custom 4,160V squirrel cage motor from stock, mechanically modified for extreme altitude cooling within days.
An emergency breakdown of an 11 kV exhaust fan motor threatened complete kiln shutdown. Menzel prepared an ex-stock 11,000V slip-ring motor with IC611 air-to-air cooling and chartered an air freight plane for immediate delivery.
Replacement of a damaged cooling water pump motor. Menzel adapted the terminal box orientation and shaft coupling dimensions in Hennigsdorf, completing full-load testing before express dispatch to Japan.
Key answers for technical directors, procurement managers, and maintenance engineers.
Standard stock motors from 75 kW to 20,000 kW can be prepared for dispatch within hours. If custom mechanical adaptations (such as shaft turning, mounting flange fabrication, or terminal box relocation) are required, our Berlin factory completes engineering work in days or weeks, compared to 6–12 months for OEM production.
We require the nameplate parameters (power, voltage, speed, current, duty cycle), dimensional outline drawing (center height H, shaft diameter and length, mounting hole dimensions A and B), and load type (pump, fan, compressor, mill). Our engineering team performs full mechanical and electrical verification.
Yes. Our in-house logistics team handles ATLAS export declarations, BAFA export licensing, consular legalization, ISPM 15 seaworthy/air-freight packaging, and global air charter logistics under C- and D-Incoterms 2010.
All emergency motors undergo routine testing according to IEC 60034 in our in-house 25 MW test laboratory. Full load testing, vibration analysis, and insulation resistance checks are certified prior to dispatch.
Our engineering team is ready to evaluate your technical data, match existing foundation footprints, and arrange rapid worldwide dispatch 24/7.
